Lawrence, in the county of Essex and Commonwealth of Massachusetts, haveinvented certain Improvements in Methods of Assembling Parts of Bootsand Shoes, of which the following description, in connection with theaccompanying drawings, is a spec fication, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to methods of assembling parts of boots andshoes.

It is a common practice to prepare the parts of a boot or shoe for thepulling-o er and lasting operations by bringing them to gether andsecuring them at the heel. 'l a present invention contemplates a no :1procedure for performing this asseml'iiiug operation in an ellicientmanner. The pwmedurc is preferably carried out by the aid of mechanismsuch as is hereinafter des ribed, but it will be understood that it maybe practised with the aid of other nicchansiu and that the several stepshcicinatte-r mew ti oncd may, if desired, be performed by hand.

As is WQll-lx'llOWlL, the parts; brought together in the assembling"omration commonly comprise a lined upper. 'a counter and an innoi'solo.In assembling the parts the counter is inserted beneath thelining of theupper at the heel, the last is placed within the upper and the inncrsoleis placed upon the bottom of the last, and the upper and counter thensecured to the innersole by a tack driven through the upper, the counterand the iuncrsole at the extreme rear of the heel. It is particularlyimportantin the assembling operation that the counter be brought intoclose relation to the end edge of the inncrsolc before the parts aresecured together. An improperposition ot' the assembled counter isordinarily not remedied during the following openuions, so that a shoewhich has been thus improperly assembled is impaired in value. Animportant feature of the procedure hereinafter described accordinglyconsists in press ing the counter not only down upon the face of theinnersolc, preferably sustained upon ing the endsof the counter a last,out 2: againstthe rear e olthe inucrsole and the rear face of the lasthe: tore securing it to said mnersole. In press:

ing the counter againstthe rear face of ther lastor down upon the face ire inner-sole, there is ordinarily a tendez" spread the ends of thecounter and ac them llO'Wn below the side edgesof the the cone of thelast. objectionable more p articx imposes upon the laster thedisplacement is .lariy in that it "cs-sity of raisinto position abovethe innersolc before lasting. According to the pr int procedure, thevends of the counter are held from downward m ir'vc mcnt past the sideedges of the innersolc. while the counter is mine: pressed. in properrelation to the inucisx .e and occur: thereto.

in the manufacture of some kinds oishocs, partimlarly in the better 5.,known as welt shuns. it is desirable to secure the parts of t shoe tothe rear face of the last. in important bject 3 th i (-l'SiI-lfifl :21 ivi-nit later l i'li lf of thescani at the pullmo-mcz' is inserted afterhe mttoni ot the last. and hetero ;t the rear edge of the inncrsolc.After said fastening has been inserted, the upper strained over the rearedge of the innci'solc and scmufcd to the iuncrsolc. The upper betweenthe two fasteuings is thus bi'tuight closely against the rear face or"the last.

In the drmvings, which illustrate a ma chine by the aid of which thepc'nt method may be conveniently practisv Figure l is a. view in sideelevation at the more important parts of the machin Fr 2 1s a View inhorizontal se tion on tac line w-;. of Fig. 1; Fig. 3 a view in verticalsection showing parts of the machine im' medial'ely adjacent to the lastoperated upon; Fig. 4 shows a shoe after being assembled, and Fig. 5shows a shoe provided with a straight counter before the completion ofthe assembling operation.

Referring to the drawings, the reference 5 numeral 3 indicates asuitably journaled shaft arranged to be given one complete rotation atthe will of the operator by the actuation of a treadle rod 15. Below theshaft 3 the frame of the machine is provided with a horizontal table 21in Which. is formed a groove adapted to receive a stem 22, the ior- Wardend of said stem constituting a rest 24L- arranged to be ged the heel.end of a shoe. A. stop 26 is mounted upon. the frame in advance of therest in position to bear on the sole of the shoe, the lower face of saidstop being corrugated and the stop being arranged for verticaladjustment. A horizontal guideway 28 is formed upon the frame below therest 24 and the stop 26,:1nd a post 30 is mounted to slide upon thisguidew ay. A vertically adjustable sleeve is arranged Within the post30, said sleeve supporting a rod 36 constituting a last supporter. Theadjustment permitted the sleeve 32 allows the position of the upper endof the last supporter to be varied to accommodate different heights oflasts. The last supporter 36 is engaged by a lever 42 which is forcedup- W'ardly by an adjustable coiled spring 4%, "the last supporter beinthus yieldingly sus tained to provide for slight variations in height ofthe last. The pressure with which the innersole is clamped upon the lastis controlled by the spring 46. A rod 54 is ar ranged to be actuated byacam upon the shaft 3, this rod hearing at its lower end yieldingly uponthe lever 42.: The rod 5 is normally in a depressed position in which 1the lever 4:2 is held down, and when the rod 54 is automatically raisedspring #3 raises the last supporter pressing sole Y the against the stopThe ertical adjustment permitted the 26 allows the height at which thelast is i id to be varied. Two levers 74 are pivoted upon the table 21at'opposite sides of the stem 22. The forward. ends of the levers 7-4,carrying the work engaging members 82, are moved against the sides of.the work by a Spring 78, said members 82 being arranged to engage theupper upon opposite sides adjacent to the ends of the counter. The rearends of the levers Mare engaged by a lever 86, said lever 86 beingactuated by a cam upon the shaft 3. When the I lever 86 is movedrearwardly,.it will be seen that the Work-engagin members 82 areindepend cntly and yieldingly held. against the work Y he spring 78. l

as carrier 62 for devices to be described pivoted at 63 upon the frameand is automusically owillated by a cam upon the shaft the lower end ofthe carrier in its forward mtwcnient. waving downward in a curved workmore easily, and its forward edge is concave or crescent-shaped. Itfrequently happens that the rear seam of an upper does not extend quiteto the heel seat edge of the upper so that a siit is left in its edge atthe extreme rear. The crescent shape of the Wiper 88 is of advantage inpreventing the tack-driving mechanism hereinafter described from drivinga tack through this slit and consequently failing to secure the upper tothe innersole. The Wiper in moving over the Work tends to gather towardthe longitudinal central line of the last the portion of upper actedupon. 1

A casing 90 is mounted upon the carrier 61-, said casing inclosing adriver bar actuated by a lever 98 pivoted upon the frame andautomatically rocked by a cam upon the shatt 3 cooperating with a springarranged, to depress t e forward end of the lever.

The stem 22 is provided with a longitudinally arranged driver passageterminating in the rest 24 and the driver bar 108 is arranged to work insaid passage and to drive a tack part Way into the rear of the shoe at apoint adjacent to the cone of the last. The

rest 24 and the driving mechanism operating therein are verticallyadjustable in order to ivary the position of the tack thus driven intothe rear face of the last. This vertical adjustment of the stem 22permitsthe end tack to be driven, if desired, closely adjacent to rearseam during the pulling-over opcra-- tion. As will be obvious, the endtack co A tacit strip is intermittently fed through a-- operatoslwiththat driven through UPPPL' and mnnlor into tho innorsolo to holdsecurely i 'n displacement the portion of the uiipor l in 5 betweenthem, and by placing r the 0nd tori: :lgo to the (zone of the last aspossililo, the rOa sham is cti'erlually held 'l".-oin, ois'placemo Tinarrang ent of the parts is preferv h that tho lflf'li drivou hy thedriver har his is either per-p0udirular to the suri; A in 'ahi-i-h it isdriven or is inrlinial to ward this solo oi the last. ilicoordingly inthe wmstrurtiim shown tho stem 22 and its driwr iinSSflg-{U iii-0inclined upwardly and will 'l io toature of driving tho tat-k i t l 'il' l tho solo of tho last is of t iii that tho tendoncy to upward of ofthe upper producsrd by the in. 3' loving over tho edgo of the last a i vsoii 113M ir-nds to draw the upper closely against tho last in thevicinity of a tack thus inserted the end oi the last. it will be obviousFig. 3 that. it the tack ore otherwise arrangrd this etl'ert might nothe sccurwh tor otvainpl i ii? the tack wort inclined in tho d3 towardthe cono of i u'iovieniont of tho upper t rouse it to he moved away inla t slid in the x'irinily of the tank.

It will be understoodthat the straight counters are in temper when used, so that they mayreadily conform to the shape of the end of the last, and so that theirupper edges may be bent over as stated. It, is n common practice tosecure a straight counter throughout its length to the upper lining bymeans of adhesi ematerial, when said counter is planed within the upper.As will ho obvious this insures that the rounter will ren'uiin in theposition which is given it; within the npprr. The parts of a boot; orshoo having heen brought together upon a last, the last is placed uponthe heel pin of the machine shown. and may he then moved by handrearwardly against the rest 24'. The counter and upper are thus broughtinto close relation to the rear face of the last. If desired, thesubsequent vertical movement of the heel pin may be depended upon toraise the Work against the stop 26. It is preferred ordinarily, howrvvr,to hold the work manually against the stop 253 and rust 24 holoro themachine is started. sinro thoroliy lho position of tho Work withrolation to tho remaining Kirk-engaging dovii'os may lie manuallycontrollm'l.

in tho further mommvntot the main shall liar u rlrongaging members 32are The devices acting upon the Work at the heel and more particularlythe wiper and presser tend to spread apart and move the ends of thecounter downwardly toward the cone of the last. This is objectionable onaccount of the necessity of bringing the counter ends back into positionbefore lasting. It is particularly disadvantageous where a flangedcounter is used since, if the corners of such counters are depressed below the edge of the innersole, they cannot be brought back into positionby the laster except at the expense of some trouble. It will be borne inmind that the flanged or molded counters are quite stilt and if theflanges of such counters are caught at their ends, below the side edgeof the innersole, they must be manually raised before lasting, in orderthat the counter may be brought closely against the sides of the last.An important function of the work-engaging members 82 is to prevent theends of the counter being moved downwardly below the edge of theinnersole.

The Wiper and presser cot perate to bring the upper into close contactwith the last and to form a Well defined edge at the rear of the heelseat, so that in lasting the operator starts with a heel seat inconsiderably better shape than is commonly produced in assembling byhand. H e is thereby enabled to form better heel seats and also toproduce them with less e'dort.

The machine herein shown and described is claimed in an applicationfiled August 15, 1906, Serial No. 330,705, of Which the pres entapplication is a. division.

Having described my invention, what I claim as new and desire to secureby Let- 11ers Patent of the United States is 1. The method of assemblingparts of boots and shoes which consists in supporting an. inuersole uponthe bottom of a making last, arranging an upper and counter about thelast in unsecured relation thereto, holding the ends of the counteragainst the sides of the last, then pressing the counter against therear face of the last adjacent its tread face and against the rear edgeof the inncrsuie, pressing the counter against the the inncrsoie andthereafter ,ng the counter to the innersolc,

The method of securing a counter to an innersole in assembled relationupon a last which consists in holding the ends of the counter againstthe sides of the last, then pressing the counter against the rear faceof the last adjacent to the bottom of the last and pressing theinnersole against the counter, and thereafter securing the counter tothe innersole.

3. The method of assembling parts of boots and shoes which consists insupporting an innersole upon the bottom of a makiug last, arranging anupper and counter about the last in unsecured relation thereto, holdingthe rear of the counterin close relation to the end of the last at apoint re moved from the sole, pressing the sides of the counter againstthe sides of the last, thereafter pressing the counter against the rearface of the lastat the sole edge and securing the counter to theinnersole.

4. The method of assembling parts of boots and shoes which consists inarranging an upper, a molded counter and an innersole in loose relationupon a making last, pressing the flange of the counter against the faceof the innersole at the extreme rear of the heel, thereafter securingthe counter and upper to the rear face of the last, straining the upperover the rear edge of the last and thereafter securing the upper andcounter to the innersole at the extreme rear of the heel.

5. The method of assembling parts of boots and shoes which consists insupporting an innersole upon the bottom of a making last, arranging alined upper and a counter about the last in unsecured relation thereto,wiping the upper and the ends of the counter forwardly along the sidesof the last and holding them, securing the upper and counter to the rearface of the last, Wiping the upper and counter over the edge of the lastat the rear end thereofland inserting a fastening through said upper andcounter into the innersole.

In testimony whereof I have signed my name to this specitication in thepresence of two subscribing witnesses.
